LAMP-BURNER.

SPECIFICATION forming ypart of Letters Patent No. 275,901, dated April 17, 1.888.

Application filed February 5, 1883.

To all whom 'it may concern:

Beit known that I, JOHN B. GEEENHALGE, of Blackstone, Worcester county, Massachusetts, have invented a new and useful Improvement in Lamp-Burners, of which the following is a full, clear, and exact description.

My invention relates to that class ot' lamphurners that are provided with means for extinguishing the flame of the lamp in case the lamp should be accidentally upset; and it consists of the construction, arrangement, and combination ot' parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ot' this specitication, in which similar letters of reference indicate corresponding parts iu all the figures.

Figure lis a side elevation of a lamp and lamp-burnerprovidedwith myinvention. Fig. 2 is a perspective view of the slotted plate plates over the lamp-wick, and Fig. 3 is a perspective view of one of the extinguishing-plates removed from the burner.

The main parts ofthe burner A may be of any approved construction.

b b are the extinguishing-plates, that are hinged under the dome C, near the wick-tube a, and are formed or provided with the arms e c, which project outwardly, as shown clearly in the drawings, and pass through the diagonal slots c c, made in the plate d. This plate d is formed with the stem d', which passes down through the llange g ot' the burner, where it is turned to forni a hook for the attachment thereto of the upper end of the rodj". This rodfreaches down the bowl-handle and base ofthe lamp and rests upon the table or other support ofthe lamp when the lamp stands upright, as shown in Fig. 1, and is of suehlength relative to the height of the lalnp that when the lamp is in upright position it lifts the plate d, causing the slots cc to open and hold open the extinguishing-plates b b, as shown in (No model.)

Fig. l. The rod is guided bythe loopszt", formed in the rings h h', and is formed with the study', and upon the rod between the stud j and the eye 'i is placed the coiled spring 7r, which serves, should the lamp be upset, to force downward the rod f, which will draw downward the plate d and cause the diagonal slots c therein, acting upon the pins e e, to close the extinguishing-plates 'b b over the wick, and thus instantly extinguish the tlanie. The stud j serves also as a means by which the rod j' may be held from downward movementby one nger ofthe hand when the lamp is lifted ott from the table or other support.

Constructed in this manner it will be seen that all danger of contlagration from the upsetting of lamps is obviated, since the extinguishing-plates will close over the wick and put out the flame instantly upon the lamp tilting from its support. Besides, the device is cheap and may be applied to all forms oflamps.

Instead of having the rod f pass down the outside ot' the bowl and handle ot1 the lamp, the handle might be made hollow and the bowl provided with a tube, through which the rod might be passed down to the face of the lamp, and thus conceal the rod.

I am aware that it is not broadly new in lamp-burners to use hinged hoods adapted, in case ot'a fall, to be operated by a weight or spring; but

What I. do claim as new and of my invention is- In a. lamp-burner, the plate d, having diagonal slots c c, converging upwardly toward each other, and having a stem passing through the burner-ange g, in combination with theplates b b, hinged near the wck-tube under dome O, and provided with arms e e, passing through said slots, as shown and described.
